The mechanical fine impact mill or centrifugal mill is usually operated in the form of a pin disc mill, blast mill, wing beater mill or grooved disc mill. Many products and finenesses for a wide variety of applications are processed with the universal mill, with a wide range of rotor and stator combinations that can be easily changed.

The invention concerns a beater mill with preliminary beaters, of the type for drying and grinding lignite (sludge) in which the group of preliminary beaters extends transversely, at 90° to the striker wheel axis.

The CSM classifier mill combines a mechanical impact mill with an integrated dynamic air classifier. The grinding is performed between a peripheral grinding track and the rotating beater gear. Due to the integrated classifier wheel, grain sizes free of coarse particles can be achieved without the disadvantages of an external grinding and ...

The N 535.43V beater wheel mill is the biggest one built by ALSTOM Power to date. It has an overall height of ca. 12 m, which is as tall as a four-storey building. There are 16 beater wheel mills of this type in the two blocks of the 1100 MW power plant in Neurath, Germany

Beater wheel mill. Beater wheel mills are designed to prepare a coal powder air-fuel mixture for combustion in furnace chambers of coal-freed power plants by coal drying, pulverizing, classifying and transport. Their multipurpose function usually results in operation instability accompanied by unacceptable vibration. This usually is a ...

The beater wheel mill grinds the fuel to the required fineness and evaporates excess moisture from the fuel, while also ensuring the coal-air mixture is drawn into the combustion chamber. The bearings must withstand the harsh conditions at the limiting operating speeds, loaded both by external loads and by the mill wheel's unbalance.

Beater wheel mill for the pulverising of raw lignite The angle by which the base plate (11) is inclined to the horizontal is adjusted to the product for milling in such a way that when the product enters the beater wheel (3) it is distributed over...

pulverized coal boiler. In the beater mills, other solids, such as limestone, dolomite, sulfur and lime are also ground. The dimensions of the beater wheel mills vary with the size of the power plants. The biggest beater wheel mill and its wheels supplied buy us has a diameter of 4,100 mm diameter.

The only reason that there is a basement under a beater room is to provide a place for the motor and the lineshaft that drives the beaters and jordans, on the floor above. As a consequence, the distance from the floor to the ceiling is only enough to make room for the drive motor and the lineshaft. This provides little head room for the oiler ...
